Changing the one-line ribbon

The items on the overflow ribbon can be moved to the visible ribbon by right-click and choose Pin to Ribbon.

Buttons on the single line ribbon can be moved off to the overflow list with the ‘Remove from Ribbon’ option.

Moving or adding other buttons around takes a visit to Customize Ribbon (right-click on the single line ribbon).

Shortcuts

Alt based ribbon shortcuts are the same on the Simplified Ribbon.

The bad news

The current builds have some worrying changes. There’s greater white space between emails and items in a folder list. An email takes up about 10 pixels more in the new interface than the old which means less emails or folders visible on the screen.

The Simplified Ribbon and other changes have reduced the vertical space used but those savings are wasted on unnecessary spacing elsewhere. It’s hard to understand why Microsoft thinks it’s better to show less on the screen. Probably pandering to less experienced users without considering the needs of Office users with decades of experience.
